education in australia

I'm finding some of my classes really interesting because I am learning about the education system in a different country. It was really interesting to learn that they have the curriculum and the hidden curriculum like we do in Canada but they have added in their curriculum values to teach. This is a very controversial issue here and for the most part people I have talked to, think there is no place for it. How can schools teach values to such a wide range of cultural backgrounds. When you come from a certain culture you grow up with certain values and then you go to school and are taught a different set of values that may contradict those of your parents. The values that are listed in the curriculum are listed on this site. Although they are basic values that sure we would try and instill in the children I found it really odd that they are part of the curriculum here and that you are suppose to teach them. This came about because alot of people were taking their children out of public schools and putting them in private schools and the gov. wanted to stop this and supposedly this was suppose to do it. I don't know what to think... you have to teach values or you should teach values in the hidden curriculum. So what is the difference? The have to and the should.
